- Sensitivity: Sensitivity determines the sonar’s ability to detect fish and other underwater structures at different depths.
Frequency: The frequency of a sonar unit affects its performance based on the fishing environment. Lower frequencies (typically around 50 kHz) penetrate deeper waters and are ideal for locating fish in deeper lakes or oceans, but they provide less detail. Higher frequencies (200 kHz and above) offer more detailed images and are better for shallow water fishing, allowing anglers to distinguish between different species and structures but with limited depth penetration.
Sensitivity: Sensitivity refers to how effectively the sonar can detect echoes from objects underwater. Higher sensitivity settings enable the detection of smaller fish and subtle underwater features, which can be crucial in identifying active fishing spots. However, too much sensitivity can lead to clutter and noise in the readings, making it harder to isolate relevant signals. Finding the right balance is essential for maximizing fishing success.
